I‘m planning on similar mods to max out fuel system. Any thoughts about doing a few dyno pulls?
That’s the plan eventually, but I need to find a decent local shop first. I want someone reputable with the VR30DDTT to clean up the tune while it's on the dyno, rather than just doing pulls.

Level 1 Z1 tune was solid, but I recently added lower downpipes and a heat exchanger and moved to the Level 2 tune. It took three revisions to finalize, but I am happy with the result. Logs look great, clean timing, no knock, and safe AFR. I am basically maxed out now; pushing further would require an upgraded fuel pump and clutch.
Did you wrap your downpipe?

what‘s the process for that? Do you have an unlocked ECUTEK tune for the dyno shop to make changes or will you send the dyno results to the original tuner for remote changes?

Loaded the Lvl 2 Map Rev 1.
AFR avg 11.6 so nice and safe
The throttle response is delayed, is this something you witnessed? About 1.5secs from demand % to actual %

The delay is likely a mix of the ECU ramping power to protect the drivetrain/traction and the physical time needed for the turbos to spool. In my logs, I see about a 0.5s lag for 'Actual Torque' to catch up; if you’re feeling a full 1.5s, it’s likely heavier torque management or traction control intervention.

Your safe 11.6 AFR shows the fuel system is handling the load well during that ramp. You should send in a log of a 3rd gear pull (with TCS off) so the tuners can compare 'Torque Demand' vs 'Actual Torque.' That will show them exactly how the ECU is managing your input and if there is room to sharpen it up.

Yeah definitely combine. The TQ demand vs Actual + throttle demand vs position= 1.5 second delay.

This is just Rev 1 so far.
